高粱育種研究

Abstract

為育成釀酒用高粱雜交品種，進行糯性高粱雜交選種試驗，糯性高粱雜交種之株高範圍為77-178 cm，穗長範圍22-34 cm，百粒重範圍為1.8- 3.1 g，穗重範圍為58-118 g。牧草用及帚用高粱雜交種株高範圍為299-322 cm。牧草用高粱經篩選12 個優良品系 (台中牧高育1 號~12號)，株高範圍為187-294 cm，單株莖桿重範圍0.1-0.34 kg，單株莖桿汁液量0-100 ml，莖徑範圍11.74-20.43 cm 及糖度範圍0-11.65 °brix，部分品系具有在栽培潛力，將持續進行栽培觀察試驗。 In order to breed sorghum varieties for wine making, the hybrid sorghum selection experiment were carried out. The plant height of sorghum hybrids were 77-178 cm, the spike length were 22-34 cm, and the 100-grain weight were 1.8-3.1 g and the spike weight were 58-118 g. For hybrid forage sorghum the plant height were 299-322 cm. Sorghum for forage had been selected 12 excellent lines (TCF No. 1-12), which the plant height were 187-294 cm, the stalk weight per plant were 0.1-0.34 kg, and the stalk juice volume were 0-100 ml, the stem diameter were 11.74-20.43 cm and the sugar content were 0 to 1.65 °brix. Some lines had potential for cultivation, and the cultivation observation test will continue.
